Caracalla

Caracalla is examined in the discussion of the Roman Emperors who ruled between Marcus Aurelius and Maximinus. He represents the danger of confusing military popularity with political security: a ruler may be admired for energy and austerity, and may even be beloved by the army, but extraordinary cruelty can make him hated by the wider population and feared by his own attendants. Caracalla’s end therefore confirms the book’s distinction between authority that commands respect and violence that creates the conditions for assassination.

Identity and Political Setting

Caracalla appears as the son of Septimius Severus and as one of the Emperors whose conduct is used to test general principles about maintaining power. The Roman imperial office exposed its holder to a difficulty more severe than that faced by many other Princes. A Roman Emperor had to manage both the people, who preferred peace and sober government, and the soldiers, who favored a warlike ruler even when that ruler was harsh, arrogant, or rapacious. The army’s preference was not merely personal: soldiers tolerated aggression against the population because it could secure increased pay and license for their own greed and cruelty.

Within this conflict, Caracalla belonged to the group of cruel and rapacious Princes who sought to satisfy the soldiery at the people’s expense. The comparison with Septimius Severus is decisive. Both possessed qualities that could make them admirable to soldiers, but Severus combined military authority with enough political strength to remain respected and to avoid becoming universally hated. Caracalla possessed impressive abilities, yet lacked the restraint that might have converted those abilities into durable rule.

Military Virtues and Public Cruelty

Caracalla’s attraction to the army rested on concrete qualities. He was warlike, extremely patient under fatigue, and contemptuous of luxury in food and of other forms of softness. These traits made him appear vigorous and dependable to soldiers, for whom a Prince’s willingness to endure hardship and embody martial discipline mattered greatly. His austerity also distinguished him from rulers who might seem effeminate or detached from military life.

Those virtues, however, were overwhelmed by the scale of his violence. Caracalla inflicted wrongs on the people in order to satisfy the soldiery, and his ferocity became “extravagant and unheard of.” He had large numbers of the inhabitants of Rome put to death at different times, while the entire population of Alexandria was killed in a single stroke. The contrast is central to his portrait: the same ruler who could inspire admiration through endurance and military spirit made himself detestable through indiscriminate bloodshed. His courage strengthened his reputation among soldiers, but his cruelty destroyed the broader political basis on which security depended.

Caracalla’s conduct also illustrates the book’s argument that hatred and contempt are distinct dangers. His military qualities prevented him from being merely despised, but his atrocities made him hated by everyone. The result was not stable fear but a form of terror that reached even those who served him. Once a ruler’s immediate companions fear him without remaining loyal, the court becomes a source of mortal danger rather than a protective barrier.

Conflict with His Own Attendants

Caracalla’s assassination followed directly from his treatment of people within his personal orbit. A Prince cannot fully protect himself against a determined attacker who is willing to risk death, but he can reduce the likelihood of such attacks by avoiding grave injuries to officers and attendants who possess access to him. Caracalla ignored this precaution.

He had the brother of a centurion put to a shameful death and continued to threaten the centurion himself on a daily basis. Despite those threats, he retained the man among his bodyguard. This decision placed a person with both motive and opportunity beside him. The danger was not an abstract conspiracy formed far from power; it was created by the Emperor’s own choice to preserve proximity to someone whom he had grievously wronged and openly menaced.

Caracalla was ultimately slain by that centurion in the midst of his army. The setting makes the reversal especially stark. The army had admired Caracalla’s warlike spirit and endurance, yet military surroundings could not save him when his personal cruelty had turned a member of his guard into an enemy. His death shows why fixed, deliberate attacks cannot be prevented by reputation alone: a person who disregards his own life may carry out the act, particularly when the Prince has supplied a compelling grievance.

Failure to Learn the Right Political Lesson

The book places Caracalla within a larger comparison among Marcus Aurelius, Commodus, Pertinax, Didius Julianus, Septimius Severus, Macrinus, Elagabalus, Alexander Severus, and Maximinus. The purpose is not to treat every Emperor as interchangeable, but to show that rulers who followed different paths reached different outcomes. Caracalla, Commodus, and Maximinus made the fatal mistake of imitating Septimius Severus without possessing the qualities that had enabled Severus to succeed.

The lesson is not that a new or threatened Prince should choose between softness and brutality in the abstract. Rather, he must distinguish between the parts of another ruler’s conduct that create a foundation and the parts that merely preserve or glorify an already established government. Septimius Severus could combine the lion’s fierceness with the fox’s craft, keep the soldiers loyal, and remain sufficiently respected by the people that his oppression did not become universal hatred. Caracalla retained the martial side without the same political balance. His strength became excess, his fear became hatred, and his military reputation could not compensate for the enemies he created at close range.

Narrative and Political Significance

Caracalla’s story functions as a compact demonstration of the principle that a Prince must avoid both hatred and contempt. His warlike character shielded him from the contempt directed at rulers considered weak or effeminate, but his mass killings and personal threats produced hatred on a scale that no military reputation could contain. The book therefore refuses to treat popularity with the army as sufficient evidence of sound rule.

His ending also sharpens the distinction between external power and internal security. Caracalla was not defeated in the field, displaced by a rival dynasty, or overthrown because he lacked physical courage. He was killed within his own army by a centurion whose brother he had dishonored and whose own life he had repeatedly threatened. The decisive weakness lay in the political relationships immediately surrounding the ruler. Caracalla’s reign thus stands as a warning that cruelty may appear useful when directed against the people to secure military support, but cruelty without discrimination can make the ruler’s closest servants more dangerous than any foreign enemy.
